Like characters of reference indieateflike parts inthe several views.y

Referring to tie drawings, liilesignates an upright window frame and2 designates sash, el which there are two as usual, which c0- operate to close the Window openingof' the trame. See Figures 1 and 2,v lhs shown; both the frame and fh are of the usual Woodicon- .ssrlflff,t i m, then i, il; will be olirtions that the inventionis not connedto a Woodconstruction, and the frame isk provided at opposite sides thereof Withusual Window Weight enP closures 3. See Figures 1,4, 5and` 6. i.

Each of the sash 2is carried for movement with respect to the trame 1 in a similar manner, and for the purpose of brevity a detailed description of the means whereby but one ofv the sash is carried Willhe given, it being un,- derstood that the descriptionis applicableto the carrying means of bothsashandfthe reference characters relating thereto being ap@ plied to both ofsuclrcarrying means on'y the drawings.

The trame 1 is providedl with vertical opposing grooves-1i at oppositey sides thereof, and the sash 2 has attached thereto, oiropposite sides atv the lower eornersthereof, transverse lyy or horizontally alined clutch t lugs 5 which are disposed correspondingly With the plane of the sash and are slidahly engaged inthe grooves l fory vertical movement of the sash in its plane With respect to the frame 1. See Figures 2, 5, 6, and 7. The sash 2` is pro,- vided at opposite sides thereof With longitudinal grooves 6, and lugs 7 are attached to the trame 1 on opposite sides thereof and are sli dablyy engaged in the grooves 6 for cooperation With the grooves L and lugs 5 to `guide the sashfor vertical movement inits plane. See Figures 2, 1l, 6, and 13.y

Mortised into the inner faces of the opposite sides of the frame 1 adjacent thelower ends of the grooves ,tare transversely, or horizontally spaced bearing plates 8 which are provided with transversely or horizontally alined bores 9 therethrough. See Figures 1, 2, 6, 1-1, and 12. Pivotally mounted in the bores 9 or" the bearing plates 8 are clutch members 11 which are provided with clutchgrooves 12 forming a part ot the grooves 4- forengagement with the clutch Vlugs 5 to provide a pivot for angular tacevvise movement off the sash, the grooves 6 being provided With lateral openings 13 for the passage therethrough of the lugs 7, engaged inthe grooves 61Whenthe sash .i s positioned inl its'vertical'movement :tor angular inmfementr thereof, in the angular met/ement of thesash, thus permitting this au ular movement i f The clutch lugs consist of attaching portions 14 of right angle formation which are y mortised into the lower corners of the sash 2 and secured thereto and theelutch lug portions proper 5 which are connected at their lower ends to the attaching portions, as designated at 15, and which are disposed in spaced relation with the attaching portions 14. See Figure 7. Horizontally disposed screws 16 pass through bores in the clutch lugs 5 and the attaching portions 14 and are screwthreaded into the sash, and window weight cord hoolrs 17, see Figure 3, are pivotally engaged with the screws16 between the attaching portions 14 and the clutch lugs 5 and are slidably engaged in the grooves 4. The free ends of the hooks 17 are offset away from the sash, as designated at 18, and are apertured, as designated at 19, for the attachment thereto of window weight cords 21 which extend upwardly therefrom in the grooves 4 to weight cord pulleys 22 of usual construction over which they are trained for connection with weights 23 in the w ight enclosures 3 of the frame to counterbalance the sash in its vertical or bodily movement. Y See VFigures 1,2, 3, and 6.

` The screws 16 are disposed approximately at the axis of angular movement of the sash so that the weight cords 21 are pivotally connected withthe sasha'pproximately at said axis with the result that the position of the weight cords is substantially unchanged in the angular movement ofthe sash and they remain in their advantageous positions in the grooves 4. n

The clutch members 11 are provided with axial spindles 24 which project in the window 'weight enclosures 3. See Figures 1, 6, and 9. Pins 25 are secured in diametrically disposed bores rinthe spindles 24 at the outer ends thereof, and torsional springs 26 surround the spindles 24 within the enclosures 3 and have ends thereof secured with the pins 25 and have the other ends thereof engaged between lugs 27 on the inner faces of the bearing plates 3. See Figures 1, 6, 11, and 12, of which Figure 12 Vshows a spring 26 in broken lines so as not to obscure other structure shown in this figure.

In the preferred arrangement the sash 2 swings inwardly, and the springs 26 yieldably urge the sash in its angular moi/'ement into its vertical position` thus resisting angular movementvof the Vsash out of its vertical position and'counterbalancing the same .in its said angular movement. The springs 26 are ai:- ially compressed in their assembly with the bearing plates 8' and the clutch members 11 so that they 'maintain frusto-conical bearing vsurfaces 28 on the inside of the main portions or heads of the clutch members 11 engaged with corresponding surfaces 29 in the bores 9 of the plate 8, thereby maintaining the clutch members 11 in proper bearing engagement with the bores 9 of the plates 8. See Figures 6, 9, and 11.

Stop means are provided which are operative upon the clutch members 11 and oppose the springs 26 to normally position the clutch members in angular positions corresponding with the vertical position of the sash, that is, to normally. position the clutch members 11 with the grooves 12 thereof alined with the grooves 4, and consist of thefollowing. See Figures 9, 11, and 12. Formed on the clutch members 11 immediately inward of the main portions or heads of the clutch members 11 are segmental stop formations 31 which operate in the bores 9 of the plates 3 immediately inward of the bearing surfaces 29 of these bores. Formed in the bores 9 of the plates 8' in angular alinement with the stop formations 31 are stop formations 32 which abut the stop formations 31 inthe angular movement of the clutch members 11 with respect to the bearing plates Sto limit 'movement of the clutch members 11 as aforesaid and in addition to limit movement of the sash out of its vertical position and in a position where the sash lies in a substantially horizontal plane.

As aforesaid the grooves 6 are provided wit lateral openings 13 for the passage therethrough of the lugs 7 engaged in the rgrooves r6 of the sash when the sash is positioned in its vertical movement for angular movement thereof. Referring to the lower sash, this sash is provided with two pairs of transversely spaced openings 13 for the release of correspondingly disposed pairs of transversely alined lugs 7. See Figures 2 and 3. The lower pair of the lateral openings on the lower sash are out-lined by plates 33 mortised into the sides of the sash and secured thereto and provided with groove formations 34 forming part of the grooves 6. See Figures 2, 3, and 10. rli'he portions of the plates 33 margining the upper ends of the corresponding openings 13 are provided with notches 35 facing downwardly in these openings and which are engageable with the lowermost pair of lugs 7 in the angular movement of the lower sash to position this sash in an intermediate or ventilating position of its angular movement, as shown iny broken lines in Figure 3, it being noted that when so positioned this sash is positively positioned Iso that draughts of air cannot change the position of the( sash. Engagement of the notches 35 with the associated lugs 7 is effected by first swinging the sash on its pivotal anis to its Ventilating position and then engaging the notches 35 with the associated lugs 7 by downward movement of the sash, the sliding engagement of the clutch lugs 5 with the grooves 12 of the clutch members permitting this movement. Further inward angular movement of the lower sash or movement of the same into its vertical position these portions of the frame are cut away about the clutch members ll, as designated at 86 in Figures 2, 3, andi 6, to limit bodily movement of the sash in their planes While they are out of their vertical positions by engagement with the ends of the clutch lugs 5, this engagement permitting sutlicient bodily movement of the lower sash inits planete engage and disengage the notches with the associated lugs 7.

The openings 13 ofthe upper sash 2 extend completely across the'sides of` this` sash so kthat this sash may pass cert-ain lugs 7 associated with the lovver sash 2 as clearly shown' in Figure 2.

lVhen both of the sashes 2 are in their closed positions they may be looked in a usual manner by means of a' usual Window latch 87, as shovvnin Figures l and 2.
